BREAKDOWN BREECH-LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 495,639, dated April18, 1893.

Application filed August 18, 1892.

To all whom it may concern.-

Be it known that I, GUSTAV ADOLF SACHS, a subject of the Emperor ofGermany, and a resident of Eugene, in the county of Lane and State ofOregon, have invented certain new and useful Improvements in Firearms,of which the following is a specification.

This invention relates to certain new and useful improvements on mypatent on breechloading fire-arms, No. 353,432, issued to me on the 30thday of November, 1886.

The object or my invention is to provide a new and improved lock tofacilitate the detaching of the barrel from the stock, to provide meansfor automatically cooking the gun, to provide anautomat-ically-operating safetydevice and an indicator to show whetherthe gun is cocked or not.

The invention also consists in the construction and combination of partsand details which will be fully described hereinafter and finallypointed out in the claims.

In the accompanying drawings, Figure 1 is a top-view of the breech-partof my improved breech-loading fire-arm. Fig. 2 is a side-view of theparts, showing the breech open. Fig. 3 is a vertical longitudinalsectional view showing the breech closed. Fig. 4 is a planview of thestock, parts being shown in section on the line 4 4, Fig. 3. Fig. 5 is avertical transverse-sectional view, on line 5 5, Fig. 3. Fig. 6 is atop-view of the trigger-plate, parts being in section. Fig. 7 is aninner sideview of one lock-plate. Fig. 8 is a view of the inner side ofthe fore-arm. Fig. 9 is a vertical longitudinal sectional View of thesame on the line 9 9, Fig. 8. Fig. 10 is an inner sideview of thecocking-slide. Fig. 11 is a sideview of the same.

Similar letters of reference indicate corresponding parts.

The barrels A are provided a short distance in advance of the breech-endon the under side with 3. lug A provided with a notch a in its front endand at the breech-end with a hook-lug A having a notch a at the rearend. A recess a is formed between said lugs. Some distance in advance ofthe lug A, the barrels are provided on the under side with a lug Aprovided in its front end with a notch a as shown in dotted lines inFig. 9. The fore-arm B which is made of wood has a plate B in- SerialNo. 443,389. (No model.)

sorted in its inner surface and said plate is provided with atransversepiece B having a curved recess B that fits on the roundedhinge-parts C at the front end of the breechblock 0 so as to turn on thesame and on the hinge pin 0 at the front of said breech-block. At thebottom of the recess B a shoulder Z1 is formed for the purpose as willbe set forth hereinafter.

In a recess at the front end of the plate B a sliding latch-pin B isarranged that is acted upon the helical spring B arranged between thefront end of said recess and the head of said latch-pin, so as to pressthe pointed end of said latch-pin through the front end of the slot b,so as to adapt said latch-pin to engage the recess or notch a in thefront end of the lug A of the barrel. To fasten said fore-arm to thebarrel, it is only necessary to place its front end upon the roundedhinge-end O of the breech-block C and then press the said fire-armagainst the under sides of the barrels. The latch pin B then snaps intothe notch a of the lug A of the barrel and locks the fore arm to thebarrel. The fore-arm can easily be removed, all that is necessary beingto pull its front end outward, when the beveled edges of the notch aacting 011 the point of the pin B force said pin into the recess againstthe action of the spring B.

To the under side of the breech-block a cocking-slide D is arrangedwhich consists of a plate having a longitudinal guide-slot D for aguide-pin and is provided atits rear end with a slot I) and with aflange D, at each side of said slot D which flanges project into thelock chamber. At the front end said cocking-slide is provided with aflange D on which the edge b of the rear end of the plate B in thefore-arm can act. When the barrels are swung into open position,asshownin Fig. 2, said edge if acts on the flange D of the cocking-slideand moves the same in the direction toward the rear, causing the flangesD to act on the hammers E which are mounted on a pin E in thelock-chamber, which hammers are pivoted on arms T projecting from therear end of the lock-chamber. Said hammers are each provided with twoshoulders e and e. A bent spring F is provided for each hammer E, and ofeach spring one end rests against the shoulder e of a hammer and theother end rests against the shoulder f of a trigger-sear F mounted on apin F, also held on the arms T, the front end of which trigger-searengages a shoulder e of a cone sponding hammer. Each trigger-sear isprovided at its rear end with an inwardly-projecting arm F which entersa notch g of the corresponding trigger G, which triggers also swing onthe pin F.

Each trigger is provided at its inner end with a lug G which can abutagainst the safety-bolt II projecting through the longitudinal slot 1 ofthe breech-tail I into the lock-chamber, which safety-bolt is fastenedto and projects'from the plate or safety-slide H that is mounted on theouter surface of the breech-tail I, and is provided at its lower endwith a series of notches h on its under side, which notches are engagedby pointed ends of a locking or safety-pin J arranged in a suitableaperture in the stock and guided in the same, which safety-pin ispressed outward by the helical spring J. The outer surface of the lowerend of the safety-slide H is serrated, as is shown at h in Fig. l, toprevent the finger from slipping while manipulating the same. The wordSafe is engraved or etched on the upper surface of the breech-tail insuch a manner that when the safety-bolt H is in such position that thelugs G of the triggers abut against the same, the upper end of thesafety-slide H does not cover the word Safe, and when the safety-slideII is moved up so as to bring the safety bolt l-I out of the path of thelugs G of the triggers G the word Safe will be covered.

Above the upper end of each hammer F an indicator-pin K is arranged inan opening of the breech-tail, which pins are pressed inward by springsK surrounding them. Said pins K are provided at the inner and outer endswith heads, the outer heads fitting into recesses in the breech-tail.When the gun is cocked the upper ends of the hammers E press on theinner heads of the indicator-pins K and press said pins outward, so thattheir upper heads project from the upper surface of the breech-tail,thus showing that one or both hammers are cocked. As soon as the gun isfired or uncooked, the springs K draw the indicator-pins inward, so thatmarksmen can at all times tell which hammeris cocked.

The firing-pins L are provided at their inner ends with heads L that areguided in recesses M, of the lock-plates M and by recesses f thebreech-block and on said heads L the hammers E can act. A stirrup N ishinged at the ends of its shanks to the safetybolt H and its closedfront end is arranged between the two hammers and adjacent to the lever0 which passes through a slot in the barrel locking belt]? that entersthe notch (t in the lug A at the breech-end of the barrels. A spring Ssecured to the under side of the breech-tail bears against one end ofsaid locking-bolt P and presses the same toward the front.

To open the breech, the lever O is pulled toward the stock W, so as todisengage the front beveled end of the bolt P from the notch a of thelug A and the lever 0 while being moved toward the rear presses upon thefront cross-piece of the stirrup N and presses the same toward the rear.As this stirrup is connected to the safety-bolt H it also presses thesame and safety-slide 11 toward the rear, thereby exposing the word Safeto view. By this movement of the safety-block H to the rear, it isbrought in such a position as to rest upon the upper end of the lugs Gof the triggers, thereby preventing the triggers from being manipulated-Before the gun can be fired, the safety-slide H mustbe moved toward thefront again so as to cover the word Safe on the top breech-tail and tobring the lower end of the safety-block H in front of the lugs G. Thegun can now be fired. To open it again for the next charge, it isnecessary to pull the lever 0 back again, whereby 1n the mannerdescribed, the safety-bolt II is agaln brought into position above thelugs G of the triggers. The spring J automatically locks thesafety-slide in the different positions. The breech-block C has tworecesses m and m for receiving the lugs A and A of the barrelsrespectively. Said breech-block has a lug 0 containing a screw 19, thebeveled lower end of which can act on the front end of the lug A andwhen the barrel is swung in closed position presses the same firmlyagainst the abutment s of said breech-block. A screw 10 in the abutments also has a beveled lower end and rests on the upper surface of thelocking-bolt P and serves to adjust the same to bring it in properposition in the slot of the abutment through which it passes, thuspermitting of adjusting said locking-bolt P to be in proper position forengaging the notch a of the lug A V is the trigger-plate.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a breech-loading fire-arm, the combination withhinged barrels and pivoted trig gers, of a sliding barrel-locking bolt,a pivoted lever for operating said bolt, a sliding plate mounted on thebreech-tail, which sliding plate has a post against which the triggerscan strike, a spring for locking said sliding plate in differentpositions and means for shifting said sliding plate from the lever foroperating the barrel-locking bolt, substantially as set forth.
